Nissan Topic: Transmission
Some 2004-07 Nissans have frustrating transmission problems ranging from rough shifting between gears, hesitation while accelerating and sudden stops or jerking.
The transmissions of some 2005–2010 Nissan vehicles are under attack from radiators. Cracked radiators are leaking coolant into the transmission, and when it mixes with the transmission fluid it creates a toxic hell stew that irreversibly damages everything around it.
For a while cracked radiators were the number one enemy of Nissan transmissions, but these days it appears the transmissions are their own worst enemy.
